Address Resolution

Subscriber addresses are validated through the USPS Address Matching Service (AMS). If a match is not found, the system will reject the entry with the following error message:

Error Code

Description

INVALID_ADDRESS

Address unrecognized (failed Address Matching Service).

Carriers may resolve an invalid address error by reviewing documentation that confirms the address is deliverable. Acceptable documentation that may be used is outlined in the Verification column in the "Address Dispute Resolution Error Codes" table below.

How to Submit an Address Resolution Request
